Jugyeom (Korean: 죽염), also known as bamboo salt, is a form of salt. It is prepared by packing bay salt in a thick bamboo stem, and baking it nine times on high temperature using pine firewood. This baking method transforms bay salt into what is considered a health food product. During the baking processes, the impurities in the bay salts are either removed or neutralized while its inorganic contents, such as calcium, potassium, iron, copper, and zinc are increased.
